Equal game (5)
I believe the answer is:
match
This clue is a double definition.
'equal' is the first definition.
(I know that equal can be written as match)
'game' is the second definition.
(eg a football match)
(Other definitions for match that I've seen before include "Suit; fixture" , "Equivalent" , "Marriage; game" , "tie" , "of little use when floodlights fail?" .)
